That the cloak doesn't make you totally invisible. So many times I've seen a stalker infiltrator running past a group of guys, and without worry I'll take my time in aiming and taking him down. These lower BR players feel that we can't see them, so they stop worrying about anyone catching them and it makes it that much easier to kill them. Not to mention the fact that whenever I use the recursion stat tracker a lot of these kills will result in an almost immediate "RAGE QUIT" notification. Feels bad man.
